Objective To explore the clinical value and safety of early enteral nutrition support in patients after liver transplantation.Methods We retrospectively analyzed the clinical data of 86 cases who used early enteral nutrition support therapy after liver transplantation between January 2008and October 2011.All of patients were uproot the gastric tube at the first day after the operation,and gradual to the normal diet.The patients who used parenteral nutrition support therapy were as the control group(n＝112).Then we compared the data of patients in the two groups.Results The early enteral nutrition is more useful to the patients after liver transplantation than intravenous nutrition [In the seventh day after the operation,the control group's ALT was (45.2 ± 12.9) U/L,AST was (40.2±9.4) U/L,ALBwas (35.6±2.5) g/L,P＜0.05].The early enteral nutrition also can decrease hospital stay and hospital costs [(14.2±3.4) d,P＜0.05].Conclusion The early enteral nutrition is useful and safe to the patients after liver transplantation.

Neurology is one of the most difficult subjects in clinical medical education.How to improve the teaching model of neurology is a crucial problem.The systematic instructional design and problem-based learning (PBL) emerge as mature teaching techniques,and having a broad application prospect.However,simple PBL teaching model has not achieved the desired results,because PBL teaching method pays excessive attention to the subjective initiative of students,but ignores the supervision and assessment mechanisms,such as assessment,feedback,adjustment,which are the major concerns of systematic instructional design.This research tries to combine systematic instructional design with PBL teaching model,and explore the position in neurology teaching.By determining the teaching target,analysis of PBL teaching,writing teaching plans,organization of PBL teaching,feedback to adjust teaching design method,the final summative evaluation is done and the teaching,was completed.After practice tips may bring progress on neurology teaching mode.

Objective:To analyze the difference in skin surface lipids (SSL) between facial skin lesions of neonates with acne and normal facial skin of healthy infants.Methods:SSL samples were collected from facial skin lesions of 36 neonates with acne (acne group) and normal facial skin of 36 healthy infants (control group) at the Department of Dermatology, Children′s Hospital, Capital Institute of Pediatrics from June 2018 to August 2018. A lipid map was constructed by ultra-performance liquid chromatography-quadrupole-time of flight-mass spectrometry (UPLC-QTOF-MS), and specific information about lipid components was obtained by multivariate data analysis. Independent-sample t test was performed with SPSS19.0 software for comparisons between 2 groups. Results:Compared with the control group, the acne group showed significantly increased relative content of glycerolipids and prenol lipids on the facial skin surface (both P < 0.001), but significantly decreased relative content of fatty acids, glycerophospholipids, sphingolipids, sterol lipids, saccharolipids and polyketides ( P < 0.01 or 0.05) .Further analysis showed that the average relative content of total lipids, diglycerides, wax esters and squalene was significantly higher in the acne group than in the control group ( P < 0.001 or 0.05), but the average relative content of linoleic acid was significantly lower in the acne group than in the control group ( P < 0.001) . Conclusion:Compared with the facial skin of healthy infants, the facial skin lesions of neonates with acne showed significantly increased total lipid content and different lipid components.

Objective To investigate the effect of acupuncture on fatigue improvement and gut microbiota in mice with cancer-related fatigue(CRF),and explore its possible mechanism of action.Methods The mice model of CRF of breast cancer after chemotherapy was established by tumor bearing and chemotherapy.After acupuncture intervention,fatigue was evaluated by general condition,forced swimming and open field experiment.Then 16S rDNA sequencing was used to analyze the structural abundance of gut microbiota in mice.Results Acupuncture could significantly improve the fatigue degree and general condition of the mice model of CRF of breast cancer after chemotherapy.At the same time,acupuncture could adjust the abundance of gut microbiota structure,up-regulate the abundance levels of Lactobacillus,Bacteroides,firmicutes,actinobacteria,and down-regulate the abundance levels of Proteobacteria and Staphylococcus.There were also differences in the abundance of flora structure among the groups,but the abundance of beneficial bacteria was relatively high in the acupuncture group,and the abundance of pathogenic bacteria was relatively high in the other two groups.Conclusion Acupuncture may play a role in the treatment of CRF by regulating the abundance of gut microbiota structure,increasing intestinal beneficial bacteria,inhibiting pathogenic bacteria,improving body immunity,and alleviating adverse reactions caused by chemotherapy for breast cancer.

As a severe clinical manifestation of nonalcoholic fatty liver disease， nonalcoholic steatohepatitis （NASH） is characterized by lipid deposition and inflammatory damage in the liver. At present， clinical medications for NASH are still in the exploratory phase， and it is urgent to make progress. Recent studies have shown that the pathogenesis of NASH is associated with circadian rhythm disorders in the liver， with the specific manifestation of dysregulated expression of liver clock genes such as BMAL1， which increases hepatic lipogenesis， reduces fatty acid oxidation， and activates pro-inflammatory factors. Therefore， improving circadian rhythm of the liver and regulating the expression of liver clock genes are feasible strategies for the prevention and treatment of NASH. Currently， some medications for NASH via activating the proteins encoded by clock genes have been applied in animal experiments， for example， the REVERB full-agonist SR9009 can inhibit the development of liver inflammation， which confirms the possibility of NASH treatment by targeting the proteins encoded by clock genes. This article summarizes the role of hepatic clock genes in regulating lipid metabolism and the development and progression of inflammation in the liver and elaborates on the recent advances in medications targeting clock genes and the proteins encoded by clock genes， in order to provide new targets for the treatment of NASH.

ObjectiveTo explore the possible mechanism of Tongdu Xingshen needling method （通督醒神针刺法） on post-stroke cognitive impairment. MethodsSD rats were randomly divided into a normal group （n=12）， a sham surgery group （n=12）， a model group （n=12）， and a electroacupuncture group （n=13）. The rats in the model group and electroacupuncture group were subjected to the wire bolus method to establish the rats model with learning memory impairment after cerebral ischaemia-reperfusion. After successful modelling， the rats in the electroacupuncture group were given electroacupuncture interventions at “Shenting （GV 24）” and “Baihui （GV 20）” once a day for 30 minutes for 14 days. The other three groups did not receive other interventions but grasp. A 5-day localisation navigation experiment was conducted on the 9th day of intervention， and a spatial exploration experiment was conducted on the 14th day of intervention to evaluate the learning and memory abilities of the rats. After the spatial exploration experiment， hippocampal tissues were taken from each group of rats， and the changes in the volume of cerebral infarction were observed by TTC staining； the changes in the morphology of pyramidal neurons and the density of dendritic spines in the CA1 area of the hippocampus were observed by Golgi staining； protein immunoblotting was used to detect the relative protein expression of the subunits of the α-amino-3-carboxy-5-methylisoxazole-4-propionic acid （AMPA） receptor including glutamate receptor 1 （GluR1）， glutamate receptor 2 （GluR2）， glutamate receptor 3 （GluR3） and auxiliary proteins TARPγ2， TARPγ8 in hippocampal tissues of rats in each group； the real-time fluorescence quantitative PCR was used to detect GluR1， GluR2， GluR3 mRNA levels in the hippocampal tissues of rats. ResultsIn the localisation navigation experiment， compared with the normal group and sham surgery group， the escape latency and total distance of rats in the model group were significantly extended （P＜0.05） at day 1， 2， 3， 4， and 5； and the escape latency and total distance of rats in the electroacupuncture group tended to be significantly shorter than those in the model group （P＜0.05）. In the spatial exploration experiment， compared with the normal group and the sham surgery group， the number of rats crossing the platform in the model group was significantly reduced （P＜0.05）， and the number of crossings of the platform in the electroacupuncture group increased significantly （P＜0.05）. The results of TTC staining showed that the volume of cerebral infarction increased clearly in the model group compared with the sham surgery group （P＜0.05）， and apparently decreased in the electroacupuncture group compared with the model group （P＜0.05）. Golgi staining showed that the number of dendritic branches of pyramidal neurons and dendritic spines in hippocampal CA1 region significantly decreased in the model group compared with the normal group and the sham surgery group （P＜0.05）. The number of dendritic branches of pyramidal neurons and the density of dendritic spines in hippocampal CA1 region significantly increased in the electroacupuncture group compared with the model group （P＜0.05）. The protein relative expression levels of GluR1， GluR2， GluR3， TARPγ2 and TARPγ8， and the mRNA levels of GluR1， GluR2 and GluR3 in hippocampus decreased in the model group compared with the normal group and the sham surgery group （P＜0.05）. The protein relative expression levels of GluR1， GluR2， GluR3， TARPγ2 and TARPγ8， and the mRNA levels of GluR1， GluR2 and GluR3 in hippocampus increased in the electroacupuncture group compared with model group （P＜0.05）. ConclusionThe Tongdu Xingshen needling method can improve learning memory impairment after cerebral ischaemia-reperfusion， which may be related to up-regulation of the expression of AMPA receptor and their auxiliary protein TARP， and promoting the synaptic plasticity of hippocampal tissues.
